I have created a alternative GC for python it's called VGC no GIL bottleneck

VGC (Virtual Garbage Collector) is a next-generation memory framework that replaces Python’s traditional garbage collection with a parallel, logic-driven model.

Instead of reference counting or tracing, VGC tracks object lifecycles using a 3-bit checkpoint system and logic gates (AND/OR/XOR), enabling deterministic, real-time memory management.

It runs under a single interpreter and partitions workloads dynamically across CPU cores and threads. Each object lives in one of three virtual zones — Red (rarely used), Green (frequently accessed), and Blue (medium activity) — each optimized for a specific mutation–lifetime balance. This design allows VGC to achieve hardware-level concurrency while maintaining memory safety and predictability.
